NC State scientist finds soft tissue in T. rex bones

...m modern specimens. Current theories about fossil preservation hold that organic molecules should not preserve beyond 100,000 years. Schweitzer hopes that further research will reveal exactly what the soft structures isolated from these bones are made of. Do they consist of the original cells, and if so, do the ...

Expression Project for Oncology (expO) completes first phase of standardized gene expression analyses

... collection efforts typically achieve a successful preservation rate of 75%. Due to close collaboration between the surgeons, pathologists, local clinical research coordinators and expO, the success rate achieved in preserving these samples was 100%. Such well-preserved tissue allows the subsequent analysis to mo...

Team of international scientists departs today to discover the unknown in China's Himalayan region

... as "protector of the sacred" has been integral to preservation in this region. One of the world's hotspots, the Mountains of Southwest China stretch over 161,500 miles and are the most botanically rich temperate region in the world with an estimated 12,000 plant species, including 3,500 found nowhere else. The...

Virginia Tech, Nanjing Institute researchers discover half-billion year-old fossils

...es tend to be deflated and squashed prior to their preservation in sandstones," Xiao said. This may change with the new discovery of Ediacara fossils from fine-grained limestone of the Dengying Formation in South China by Xiao and his collaborators. "The Ediacara fossils from China were not deflated before they ...

New antifreeze protein found in fleas may allow longer storage of transplant organs

...the organ is safely stored, there will be a longer preservation period." The hyperactive antifreeze protein produced by snow fleas is different from two other insect proteins discovered earlier at Queen's, the researchers say. "Unlike the antifreeze proteins in beetles and moths, AFPs in snow fleas break down...

Missing fossil link 'Dallasaurus' found

... that lend themselves fairly well to more complete preservation and conservation of their bones, and much slower deterioration. Mosasaur fossils, in contrast, are rarely found in large groupings, and are only found in areas once covered by seas. Remains were quick to deteriorate under ocean currents; their bodies...

Key brain regulatory gene shows evolution in humans

...gulatory sequence leading to humans that indicated preservation due to positive evolutionary selection. They also found an "evolution-by-association," in which sequences near the regulatory segment showed greater mutational change -- as if they were "dragged along" with the evolving regulatory sequence. In contr...

Paleontologists learn how not to become a fossil

...aid. "Small body size turns out to be bad news for preservation in general, and thus deep-sea species are undercaptured." Surprisingly, they found that burrowing clams living within sediments were no more likely to become fossils than similarly sized varieties that lived out in the open. Perhaps fittingly, para...

Age-related changes in DNA repair illuminate the connection between age and genetic damage

...l Press. DNA repair is essential for the accurate preservation of genetic information and to ensure the healthy functioning of cells, and a connection between aging and DNA damage has long been suspected. One line of evidence supporting the connection is that defects in certain genes needed for DNA repair produc...
